  1. AVIC-MRZ99 Custom Firmware / Testmode

    Put this testmode key onto a usb stick or sd card: TESTMODE.KEY And switch on the unit. If this doesn't bring up testmode then there is nothing much you can do. If it gets you into testmode, then you will need to find somebody else with the same model as yours and copy their PRG0 folder. You should never have deleted the PRG folders
  2. Hello. I bought a car from Japan with Avic-mrz02. I tried to replace the files with your instructions, but nothing happened. Can you help? I enclose a copy of the original firmware. And tell me how much money it costs. Thank you in advance


  3. Hello Dzo,

    Sorry to knock you over this issue since I can see that you are quite busy. 

    I was just wondering whether you still have the backup for MRZ99 ? 

    I downloaded the zip file from your post no 59 on my Sd card and then changed the script to SD/ from USB. After inserting the SD card the installer started in a red background and then changed to green and it keeps on rebooting.

    As of now my player is stuck on the screen as I have posted below but I can hear audio when I insert a Cd into my MRZ99, but I can enter testmode. Please help me !

    Also the very same SD card that I used for the backup isn't working so I don't ave any backup

  6. Hello, I have seen your posts in the forum, I have a MRZ05 also and am having problems to set it up. Please can you help me ? 

    I copy the file from the SD but when I go to the folder to paste it does not allow paste. I tried so many times. 

    Also I made a mistake that i did not back up when I deleted the original PF090JPJPN.LNG

    I would so much appreciate any help ... I have done this to my Mothers car as way to surprise her but now she is mad at me becuase it is not working !

    Thank you so much


  7. will the english file work on the avic-mrz05?

  8. AVIC-MRZ99 Custom Firmware / Testmode

    OK, last try: testmode_NX007.zip or testmode_nx064.zip
  9. AVIC-MRZ99 Custom Firmware / Testmode

    How about this: testmode_NX146.zip
  10. AVIC-MRZ99 Custom Firmware / Testmode

    I don't think that's the correct file, but you still need to be able to copy and paste. Can you try the testmode key from post #90.
  11. AVIC-MRZ99 Custom Firmware / Testmode

    The language strings should be in PRG0/APL/LANGDATA, can you not select a directory for copying?
  12. AVIC-MRZ99 Custom Firmware / Testmode

    Can you copy the NX064 directory to an sd card and post it somewhere. You can use google translate on a phone to do a live translate of the japanese messages.

    Item 9 on the first page is the file manager. This should let you copy and paste the language files to an sd card. It should be very silimar to this: There is a chance that copy and paste doesn't work without the correct testmode key.

    I'm pretty sure the zh77 is completely different to the mrz77 so it very unlikely my language file will work. Try getting into test mode and post the langdata files here and I'll take a look at them. Don't replace anything though.
  15. AVIC-MRZ99 Custom Firmware / Testmode

    Post #264 says this works on mrz06 so try it and see, make sure you backup the existing language files first.
